RR MetalMakers's RR MetalMakers YST 310 MS SHS - (90 x 90 x 4.8 mm) - 6 mtr Length is a high-quality cold-formed Square Hollow Section in YST 310 grade structural steel produced to IS 4923:2017 (Hollow Steel Sections for Structural Use). The 90 mm × 90 mm × 4.8 mm hollow square cross-section across 6 m lengths is engineered to deliver high yield strength enabling slender sections under heavy axial loads, outstanding weldability, and superior resistance to combined loading — critical for heavy engineering, crane structures, high-rise bracing, and bridge frames. Sourced from prime HR coil, processed through precision roll-forming and ERW welding, each section ensures dimensional consistency throughout its length.
